SPECIFICATION forming part of Letters Patent No. 479,089, dated July 19,1892.

Application filed April 22, 1891.

To all whom t may concern.'

Beit known that I, ROBERT GILcHRIEsT, a citizen of the United States,residing at Louis- Ville, in the county of Jefferson and State ofKentucky, haveinvented certain new and useful Improvements inFire-Grates; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to whichit appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure l of the drawings is a front view. Fig. 2 is a side view showingthe grate set out, with the fireplace and mantel removed; and Fig. 3 isa perspective View of a modified form of grate. Fig. 4 is a detail ofone of the front grate-bars. Fig. 5 is a detail, partly in section,showing the manner in which the gratebars are held in place; and Fig. 6is a detail of one of the supports for the rear portion of the bottomgrate-section. Fig. 7 is a perspective view showing the grate in place.

This invention has relation to certain newA and useful improvements ingrates, the obj ect being to provide a grate especially adapted for usein open fireplaces; and the invention consists in the novel constructionand combination of parts, as hereinafter specified. V

In the accompanying drawings, the letter A designates a fireplace, inthe opening of which is secured the grate-supporting casting B. On thevertical side portions of this casting are formed two or more lugs b,which project laterally inward toward each other.

D designates the lower grate-section, comprising the transverse end barsd d, in which are held the ends of longitudinal grate-bars d.

F is the front grate-section, comprising the parallel end castings ff,in which are removably secured the respective ends of the transversegrate-bars f. In the lower forward portion of each end casting f is abearing g, which receives the journaled ends g of the forward transversebar d of the lower gratesection. These bearings are usually formed inseparate lugs f which are removably se cured to the end castings. Theend castings fand the grate-bars f might, if desired, be cast integralwith each other; but I prefer to Serial No. 389,940. (No model.)

cast each bar separately, in order that it may readily be replaced ifbroken, for, if made in one piece, upon the breakage of one bar thewhole grate would be rendered useless. For the purpose therefore ofpermitting the bars to be readily removed their ends are cast with therecessed lugs t', which fit corresponding recesses and shouldersin theend castings, and are held in place by shouldered caps or castings K,removably secured to the end piece, and provided each with a shoulder7o', which engages the upper end portion of its respective bar. Each ofsaid grate-bars is beveled obliquely on its inner or rear face,presenting a sharp edge f upwardly, in order to ofer less resistance tothe fuel and ashes. Said bars are also disposed in different Verticalplanes, each succeeding bar from the top being set slightly in advanceof the preceding bar. The bars when so disposed offer less obstructionto the falling' of the fuel and also present a larger surface area,through which air is received.

In the upper portion of each end castingf is removably secured arearwardly-projecting lug Z, having a hooked or shouldered rear end,designed to engage the upper pair of lugs b of the supporting-castingand support the grate in the manner best shown in Figs. 2 and 7 Similarrecesses m are also formed lower down on the end castings, in which thelugs Z may be secured, instead of in the recesses j', if it is desiredto support the grate at a less height, or the lugs Z may engage thelower lugs b for this purpose.

K designates a lire-back, which may consist of a solid sheet of metalsupported loosely at the back of the fireplace. On the lower edge ofthis back are lugs K, upon which said back rests, and its upper edge isheld a short distance away from the rear wall of the iireplace by therearwardly-projecting lugs frz, forming an air chamber or flue S at therear, as shown.

l? l? are supports for the rear portion of the lower grate-section, andwhich are provided each at their upper portions with a perforationengaging vthe journaled end of the rear bar d of said lower section. Thelower ends of these supports are cut obliquely to rest upon the hearth,as the supports are in ob- IOO liqne position. The supports are usuallyformed with a series of oblique grooves p p therein, at any one of whichthe supports may be broken to give it the proper length for snpportingthe grate at the desired height. By pulling these supports forwardly byany snitable means the lower gratesection may be dumped. (Dwing to thepivotal connection between the two grate-sections, it is apparent thatthe lower section maybe supported at any suitable angle with regard tothe front section.

For the purpose of securing the grates rigidly to their adjustment thelower rear portion g2 ot' each end casting is provided with aperforation g3, through which may be driven a small pin or nail intointo the brick-work. During the summer months, when the grate is not inuse, the front and lower sections may be folded together and placedinside the fireplace behind the lugs I).

In Fig. 3 I have shown a slightly-modified form of the front section, inwhich the gratebars are all located in the same vertical plane.

The various parts are so arranged as to permit a free draft fromunderneath up through the fuel, so that not only the smoke, but also theashes to a large extent, may be carried up into the chimney.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The herein described fireplace-grate, comprising a frontgrate-section having an ad instable support, a bottom section having itsforward end bar removably journaled in the lower forward portion of thefront section, and adj nstable oblique supports for the rear portion ofsaid lower section, substantially as specified.

2. The grate-section comprising the end casting having shoulderedrecesses therein to receive the grate-bar ends, the grate-bars havingshouldered recessed ends engaging said recesses and shoulders of the endcastings and held therein by removable lugs or castings, and adjustablesupporting-lugs secured to the upper portion of said end castings,substantially as specified.

3. The grate-section comprising the end castings having shoulderedrecesses therein to receive the grate-bar ends and the gratebars havingrecessed shouldered ends secured therein by removable lugs or castings,said bars having the oblique rear faces and arranged in differentvertical planes, substantially as specified.

In testimonywhereof I affix my signature in presence of two Witnesses.
